Colloidal Synthesis of γ-MnS Nanorods with Uniform Controlled Size and Pure ⟨002⟩ Growth Direction

Abstract

One dimensional (1D) compound semiconductor nanostructures have unique anisotropic optical, electrical, and physical properties. Synthesis of large scale 1D nanostructures with pure crystallographic growth direction by a colloidal route and finding an easy method to prove it were significant for further exploring their unique anisotropic properties. Additionally, MnS is one of the most important optoelectronic and magnetic semiconductors. Herein, the large scale γ-MnS nanorods with completely pure ⟨002⟩ growth direction were first synthesized and convinced by solid evidence using the X-ray diffraction method. Compared with the standard diffraction pattern of γ-MnS powder, the ⟨002⟩ oriented long γ-MnS nanorods showed only the (100),(110), (200), and (210) peaks while other diffraction peaks disappeared. This study opened a door for the synthesis of the 1D colloidal nanostructures with pure crystallographic growth direction at large scale, benefiting the manufacture of a novel apparatus based on their anisotropic properties.

“…Thus, for the SSS growth, by minimizing the interfacial energy related to crystal structure and lattice mismatch between solid catalyst and solid product as well as utilizing the ligand effect on the solid catalyst, it might be possible to realize the crystallographic orientation control of 1D nanomaterials. Recently, the uniform γ ‐MnS nanorods with crystallographic orientation along ⟨002⟩ were prepared via the SSS growth, [ 11 ] which provided the guidance for further constructing controllable crystallographic orientation of 1D metal sulfide nanomaterial.…”
